Prior to this update, Bash refused to import previously exported functions whose names contained a hyphen. As a consequence, scripts that used such functions did not work properly, and Bash printed the following error message:

Previously, Bash incorrectly parsed function definitions containing a here-document that ended with the end-of-file or end-of-string character. Consequently, Bash accessed an invalid memory segment when the parsed function was copied, and Bash terminated with a segmentation fault. This problem has been fixed. As a result, Bash no longer crashes when the aforementioned function definitions are used.
